Abstract
According to one embodiment, an X-ray computed tomography apparatus includes a gantry for imaging a subject by X-ray CT and a console communicably connected to the gantry. The gantry includes a gantry body and a column unit. The gantry body has a bore into which the subject is inserted when the subject is imaged by X-ray CT. The column unit includes a first column which supports the gantry body slidably in a direction perpendicular to a floor surface and a second column which supports the first column slidably in a vertical direction.
Claims13
An X-ray computed tomography apparatus, comprising:
- a gantry configured to image a subject by X-ray CT;
- and
- a console communicably connected to the gantry,
- wherein the gantry comprises
- a gantry body having a bore into which the subject is inserted when the subject is imaged by X-ray CT;
- a column unit including a first column, which supports the gantry body slidably in a direction perpendicular to a floor surface, and a second column, which supports the first column slidably in a vertical direction,
- a first motor configured to generate power to cause the first column to slide the gantry body;
- a second motor configured to generate power to cause the second column to slide the first column;
- and
- control circuitry configured to control the first motor and the second motor,
- wherein the first column supports the gantry body slidably within a first movable range;
- the second column supports the first column slidably within a second movable range;
- and
- the control circuitry is further configured to control the first motor and the second motor synchronously to raise and lower the gantry body within a predetermined range between a maximum height of the gantry body from the floor surface and a minimum height of the gantry body from the floor surface, the maximum height is where the gantry body is located at an upper limit of the first movable range and the first column is located at an upper limit of the second movable range, the minimum height is where the gantry body is located at a lower limit of the first movable range and the first column is located at a lower limit of the second movable range.
